The default behavior now preserves the 'content-type' header, at the expense of not providing pseudo-streming in Safari, generic WebKit, and older Chrome. Applications that require streaming and already use 'prefer-stream' mode will not be affected. The 'prefer-fast' mode is now deprecated, as that behavior now matches the default. The 'allow-wrong-content-type' mode is new; it gives the same behavior as the old default in case binary streaming is essential. Fixes #8
